Set Data Usage Warning Level
If you have already capped your monthly data plan on a Xiaomi phone, you might still get surprised when the limit hits without any heads-up. The warning level tells MIUI at what percentage of your data plan it should alert you before you run out.
Set a New Alarm
Waking up on time with a Xiaomi phone means finding the right spot to add a repeating schedule, a custom label, or a different ringtone for each alarm. Many users only set a one-off alarm and miss the options for weekday repetition, vibration, or automatic deletion after the alarm rings. Getting these details wrong means the alarm either fires on the wrong days or disappears after a single use when you actually wanted it daily.
Turn Camera Grid Lines On or Off
If your photos keep coming out tilted or the horizon never lines up straight, you are probably shooting without any framing guide. Xiaomi's camera app can overlay a 3x3 grid that helps you keep verticals upright and place the horizon on a clean line. Without it, minor tilts are easy to miss on a small screen and only show up later when you check the shot on a bigger display.
Change Camera Picture Quality
If your camera storage fills up fast or photos take too long to share, the picture quality setting in the MIUI camera app is often the reason. Xiaomi's camera defaults to a high resolution that produces large files, even when you only need a quick snapshot. Switching between High, Standard, and Low lets you balance sharpness against file size for each situation.
Turn Notification Badges On or Off Per App
A red dot keeps sitting above an app icon even after you have opened every message inside it. On Xiaomi phones this badge is a separate switch from the notification itself, so muting an app does not always remove the counter. If the dot never clears, or shows up for an app you barely use, the badge toggle for that specific app is still turned on.
Change Notification Sound
When every app on your Xiaomi phone plays the same generic chime, spotting an important message in a stack of notifications gets tricky. MIUI lets you pick a different tone per notification type, and if you run two SIM cards you can even split the sound by line. The tricky part is finding where this setting actually lives, since it is buried a few taps below the general Sound menu.
Turn an Alarm On or Off
Alarms you already set on your Xiaomi phone stay stored even after you switch them off, but the toggle in the Clock app is easy to miss. If an alarm keeps ringing when you do not need it, or stays silent when you want it active, the switch next to the entry is probably in the wrong position. This affects your wake-up routine and any reminders you set up in MIUI.
Add Update Shortcut to Home Screen
Checking for a new MIUI version usually means digging through several settings screens on a Xiaomi phone. A home screen shortcut skips that detour and opens the update check directly. Without it, casual users often forget to check for updates at all.
Remove App from Folder
When a folder on your Xiaomi home screen fills up with apps you barely touch, finding the one you actually use often becomes annoying. This happens a lot with apps like Messenger or WhatsApp, which start in a folder but end up needing a spot of their own once you rely on them daily. MIUI lets you pull an app back out without deleting anything.
Turn HDR On or Off in Camera
Photos taken against bright light or in high-contrast scenes sometimes look overprocessed, flat, or slightly blurred on Xiaomi phones. This happens when HDR (High Dynamic Range) automatically merges several exposures into one shot, which also slows down capture for moving subjects.
Clear the Whole Call History
When missed, dialed, and received calls pile up on your Xiaomi phone, scrolling through the list to find one number gets tedious fast. Deleting entries one at a time barely makes a dent if you actually want a clean call log. MIUI offers a single action that wipes the entire history at once, and once it's gone, it's gone for good.
Rename a Home Screen Folder
A newly created folder on your Xiaomi home screen often just carries a generic label like 'Folder' or picks up the name of the first app you dropped into it. That makes it hard to tell at a glance whether it holds your shopping apps, finance tools, or games. Once you have several folders sitting next to each other, a clear name is the only thing that keeps your screen readable.
Format an SD Card
A newly inserted SD card sometimes won't work correctly in a Xiaomi phone, or you want to wipe an old card before reusing it. Formatting clears the card and lets MIUI set up the folder structure it needs to store photos, videos and app data properly. Once you confirm the format, every file on the card is gone for good.
Reset Wi-Fi, Mobile Data & Bluetooth
If Wi-Fi keeps dropping, mobile data stops working after a SIM swap, or paired Bluetooth devices refuse to reconnect, corrupted network profiles are often the real cause. Switching a connection off and on rarely fixes these deeper configuration conflicts. A full network reset clears every saved Wi-Fi password, paired device, and mobile data setting in one pass.
Turn Dual Clock On/Off on Lock Screen
After switching the region on a Xiaomi phone, a second time suddenly shows up on the lock screen next to the main clock. This happens because MIUI detects a time difference between your set region and your current location or SIM, and the Dual clock feature reacts automatically. You can switch it off entirely or change which region the second clock refers to.
Enlarge the Mouse Pointer
When you plug a USB mouse or similar pointing accessory into a Xiaomi phone, the on-screen pointer often stays tiny and hard to track. Large mouse pointer is a dedicated Accessibility option built for exactly this situation, especially useful for anyone with limited vision. Without enabling it, you end up guessing where the cursor sits on a crowded screen.
Add or Remove Bookmarks in Mi Browser
Losing track of a website you visited last week is common once it drops out of your browser history. Bookmarks fix this by saving the page permanently until you decide to remove it. The catch is that many Xiaomi users don't know where the bookmark list actually lives inside Mi Browser, so saved pages get forgotten or accidentally deleted.
Change Display Size
If text and icons on your Xiaomi phone look too small or too cramped, the Display size setting is usually the cause. It scales both the interface and the font size together, which can push app shortcuts around on your home screen until you rearrange them.
Pocket Mode in the Camera App
If your phone's camera keeps opening or snapping photos while it's still in your pocket, stray touches on the screen are usually the cause. Pocket mode locks the touchscreen once the sensor detects the phone is stored away, blocking accidental swipes and taps. When the camera reacts to pocket movement or the screen stays unresponsive after you pull the phone out, this setting is worth checking.
Turn On or Off Find My Device
If your Xiaomi phone goes missing and Google's Find My Device search comes up empty, the tracking toggle is probably switched off in your privacy settings. This setting decides whether your phone keeps reporting its last known location to your Google Account. Without it enabled beforehand, there is no location history to fall back on once the phone is actually lost.
Set Notification Sounds for Each App Individually
When every app on your Xiaomi phone plays the same notification tone, it gets hard to tell a messaging alert from a random app update without looking at the screen. MIUI lets you assign or mute sound per app, but the option sits inside a settings area many users never open. Here is where that control actually lives and how to change it for one app at a time.
Enterprise Mode
If you spot Enterprise mode buried in your Xiaomi settings and have no idea what switched it on, you are not alone. The feature is built for companies that want to restrict which apps or websites an employee device can reach, and in some setups it can also report device activity back to an administrator. On a private phone that was never enrolled by a company, this toggle usually just sits there unused, which raises the question of what it is doing and whether it is safe to leave alone.
Remove a Stored Fingerprint
If a fingerprint still unlocks your Xiaomi phone after you sold it, handed it to someone else, or just registered a bad scan, that print needs to go. MIUI stores several fingerprints under one name, so it is easy to remove the wrong one by mistake. Deleting a print always asks for your unlock pattern, PIN or password first, which trips up people who only remember using their finger.
Set an App Timer to Limit App Usage
Some apps quietly eat hours of your day without you noticing, especially social media or games that keep notifications pulling you back in. On Xiaomi phones there is no built-in reminder that tells you when an app has crossed a healthy usage limit. Digital Wellbeing lets you assign a daily time budget per app so it pauses itself once that budget runs out.
